I am a PT Sorter of 8 years. I work in the Oklahoma City Hub and have the highest seniority in my area. I'm having a seniority issue that my local union BA refuses to grieve for me. I have filed several grievances for the same practice, but when I called my BA to get an update, he told me that he withdrew all of them because I was wrong and he wasn't going to waste his time on it. The issue is: I have the highest seniority, but I'm being sent home against my will while people with less seniority are being allowed to stay until the end of the twilight shift. They are all PT like me. I come in 30 minutes early to set up the area and I also get 10 min for working thru break. So when it comes close to the end of the shift, I will hit 5 hours while the other sorters are about 30 minutes less. Management says they don't want to pay overtime and don't have to let me stay. I know I'm not guaranteed 5 hours or overtime. However, my understanding is that as long as all the workers hit their 3 and half, any extra work goes by seniority. And since I am being sent home early against my will when less seniority are allowed to stay, I feel that UPS is not following the seniority order. My BA also said that I am getting my extra work by coming in early and that UPS can send me home early. But isn't extra work just anything over 3 and half? And it shouldn't matter if its at the beginning or end, right?
